Add more gettext markers.

Fix typo-like error for the interpretation of the `[timeline] changeset_long_messages` configuration setting.

Partially revert r6227 (trac/core.py), as this triggered an internal error with mod_python.

The `from trac.util.translation import _` in trac/core.py was triggering a recursive import of `trac.core.TracError` via `trac/util/__init__.py`:
{{{
...
[error] File "/packages/trac/branches/upstream-trunk/trac/core.py",
line 19, in ?\n from trac.util.translation import _
[error] File "/packages/trac/branches/upstream-trunk/trac/util/__init__.py", line 31, in ?\n from trac.core import TracError
[error] ImportError: cannot import name TracError
}}}

Convert more TracErrors to the common style.
Add gettext markers.

Add more gettext markers.

On project creation, it is now possible to pass in an option for the `[inherit] file =` setting, and have the environment be a bit smarter on creation.

It will now load inherited settings when created, and not write defaults to project trac.ini except what is entered through the `initenv` console session or passed in as options to `Environment.create()`.

Command line option looks like this (can be appended to both variations of `initenv`):
{{{
trac-admin /path/to/new/env initenv --inherit=/path/to/global/trac.ini
}}}

Also includes a fix for not writing `[ticket-workflow]` when that section exists in the inherited trac.ini.

Closes #5651.

Setting height and width for header logo should now work with 0.11.
Values of 0 or -1 means the attributes will not be set.

Fixes #4696.

0.10.5dev: ported r6223 from trunk (''PySqlite 2.4.0 compatibility fix'')

PySqlite 2.4.0 doesn't accept an unicode object for the connection string anymore.

Bug or feature, the release is out, so we have to live with it...
